A rocket during launch from the Earth's surface moves vertically with an acceleration of 22m / s ^ 2. Find the cosmonaut's weight inside the cabin if his mass is 90kg.
Homework Equations
The problem belongs to "Elasticity. Moving under the action of elastic force" chapter.
General gravity relating to man = 900N;
N - G = ma?
N = m(a+g)
N = 90*(22+10) = 2880 N

I think the two are the same (as long as you got it right). Hence the addition of the ”essentially” - the remaining step being to realize that what was computed was the sought quantity.PeroK said:There's solving a problem and knowing you've solved it!
The cosmonaut's weight will decrease as the rocket moves higher into the atmosphere due to the decrease in gravitational pull.
Yes, the cosmonaut's weight will remain constant when the rocket is stationary, as long as they are on the surface of the Earth and not in motion.
The cosmonaut's weight is different on the rocket because the rocket is in motion and the gravitational force is constantly changing as it moves through the Earth's atmosphere.
Yes, the cosmonaut's weight can be measured while the rocket is moving, but it may be difficult to get an accurate reading due to the changing gravitational force.
The cosmonaut's weight does not have a significant effect on the performance of the rocket, as the propulsion system is designed to lift the weight of both the rocket and the cosmonaut into space.
